I've created a private network with DHCP disabled, and I've attached 3 instances to it. The problem is that, altough DHCP is disabled, somehow the nova list command gives me:

+-------+------------+--------+------------+-------------+----------------------+
| ID     | Name       | Status | Task State | Power State | Networks            |
+-------+--------+------------+-------------+-----------------------------------+
| ***** | backend01  | ACTIVE | -          | Running     | Ext-Net=*****; Priv-Net=192.168.1.4 |
| ***** | db-master  | ACTIVE | -          | Running     | Ext-Net=*****; Priv-Net=192.168.1.3 |
| ***** | frontend01 | ACTIVE | -          | Running     | Ext-Net=*****; Priv-Net=192.168.1.2 |
| ***** | nova       | ACTIVE | -          | Running     | Ext-Net=*****                       |

Maybe the hosting provider (OVH) has some sort of auto-config?... Anyway, what I now need to change the private IP address of 2 machines. Is it possible?

Thank you.
